they are all dumb dogs, they cannot BARK.

LIFT UP THY VOICE LIKE A TRUMPET
and shew my people their TRANSGRESSION,
and the house of Jacob their SINS.

Arise, go to Nineveh, that great city,
and CRY AGAINST IT;
for their wickedness is come up before me.

GRIEVE NOT THE HOLY SPIRIT OF GOD,
whereby ye are sealed.
–Ephesians 4:30 (KJV)–

While Paul was waiting for them at Athens,
his spirit was GREATLY ANGERED WHEN HE SAW
that the city was FULL OF IDOLS.
–Acts 17:16 (AMP)–
